Question

Renee hiked for 4 3/4 miles. After resting, Renee hiked back along the same route for 3 1/4 miles. How many more miles does Renee need to hike to return to return to the place?

Answer 1

4 3/4 - 3 1/4 = 1 2/4, which is 1 1/2 OR 1.5

Answer 2

Let

x--------> the distance in miles that Renee need to hike to return to the place

we know that

$x=4\frac{3}{4}-3\frac{1}{4}$ --------> equation $1$

Step $1$

convert mixed number to an improper fraction

$4\frac{3}{4}\ miles=\frac{4*4+3}{4} =\frac{19}{4}\ miles$

$3\frac{1}{4}\ miles=\frac{3*4+1}{4} =\frac{13}{4}\ miles$

Step $2$

Substitute the values in the equation $1$ and find the value of x

$x=\frac{19}{4}-\frac{13}{4}$

$x=\frac{6}{4}=\frac{3}{2}=1.5\ miles$

therefore

the answer is

$1.5\ miles$
